Congratulations to participants and winners of CNU Mid-Atlantic's Single-Stair Design Competition. All entries are now online for free download. The excellent entries show some of the features that single-stair buildings can offer more easily than "double-loaded corridor" buildings. 1/2

Reminder that registration for this design competition opens today -- 3 March 2025.

CNU's Mid-Atlantic Chapter is sponsoring a Single-Stair Building Design Competition for infill sites in Baltimore. All mid-Atlantic residents and students may participate. Registration is open from March 3 to April 11. Winners will get cash prizes and publicity at the awards ceremony.

Boston has announced it will upgrade traffic signals throughout the city to give priority to buses. The system tracks and anticipates bus positions, and adjusts traffic signals in real time, to minimize delay at intersections.

And the answer is: not much. Increasing a zoning limit from 7 dwellings per acre to 12 du/ac would not cause parking demand to exceed supply. On all the blocks that were studied, a majority of parking spaces were unused.

Science-fiction author and industrial-design theorist Bruce Sterling writes about the YouTube maker Laura Kampf. His essay is part fan letter, part theoretical grappling, and part aimless philosophical musing. It intersects with urban design where it discusses interventions in the public realm.

This paper blends historical narrative and quantitative analysis to reveal how Tokyo became "a paragon of street-network connectivity." Authors were Felix Vazquez, Adam Millard-Ball, Christopher Barrington-Leigh (profcpbl.bsky.social) 1/6

This study analyzes street-network patterns in all the world's urban areas. It investigates the design and development factors that affect transport CO2 emissions. Better-connected street networks, and street networks with straighter travel routes, are generally linked to lower CO2 emissions. 1/6

The overall width of roadways has a major effect on crash risk, but that effect is too often overlooked or dismissed in safety research. This study is the largest analysis of the topic to date, covering 49,000 pedestrian crossings in Paris, San Francisco, and Irvine, California. 1/
